The experimental results showed that SiC ultrafine powder was synthesized at 1500℃for 120 minutes by used rare earth lanthanum as additive. Its primary particle size was about 100nm and aggregated particle size was about 360nm and the particle shape was regulation, non-aggregation and well dispersibility. While the rare earth ceria used as the additive, SiC ultrafine powder was synthesized at 1500℃for 150 minutes but the particle shape was irregulation and seriously agglomerated and had numerous crystal whiskers.

实验结果表明：以稀土镧为添加剂时，在1500℃×120min合成工艺下，可以合成出一次粒径为100nm左右，二次粒径为360nm的SiC细粉，且SiC粉体颗粒形状规则，无团聚，分散性好；以稀土铈为添加剂时，在1500℃×150min合成工艺下，也可以得到单相的SiC，但SiC粉体颗粒形状不规则，有大量晶须存在，且团聚严重。

Levels of expression significantly increased after day 4 posttransplantation and persisted through the whole course of rejection, but levels of expression were obviously lower in the peripherial blood than those in portal vein blood. In contrast, the control group showed no expression of mRNA for perforin and granzyme B in portal vein and peripherial blood.

结果 急性排斥肝移植组术后3天门静脉和外周血中均有穿孔素和颗粒酶B基因mRNA表达，4天后表达明显增强，并贯穿整个排斥反应的全过程，但外周血表达的强度明显较门静脉血为弱，同基因对照组术后14天内无穿孔素和颗粒酶B基因表达。

Results The rejection group began to show the mRNA of perforin and granzyme B up-regulation on day 3 posttransplantation, when no histologic evidence of rejection was found. Levels of expression significantly increased after day 4 posttransplantation and persisted through the whole course of rejection, but levels of expression were obviously lower in the peripherial blood than those in portal vein blood. In contrast, the control group showed no expression of mRNA for perforin and granzyme B in portal vein and peripherial blood.

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。

The influence of the hanging orientation of cathode to the electrodepositing of diamond-nickel composite film was shown in this paper.

给出了阴极悬挂方式对金刚石-镍复合膜电沉积结果的影响，指出：当阴极完全竖直悬挂时，复合膜中无金刚石颗粒沉积；而将阴极上部远离阳极倾斜悬挂时，则可得到有金刚石颗粒分布的复合膜。

During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of testis also increase in quantity, but it is less than that in ovary, they disintegrate after sexual differentiation. The big grana always exsist in course of sexual differentiation, but small grana don\'t appear.

分化时精巢细胞的超微结构显示线粒体和内质网数量也有增加，但不如分化中卵巢细胞的数量多，分化后线粒体和内质网解体，在整个分化过程中大颗粒一直存在，无小颗粒出现。
